    • This invention disclosed is a comprehensive power quality controller for substation in the electric power system and includes a Thyristor Controlled Reactor (TCR), pure tuned passive filter Zf, additional inductor L active power filter (APF), and a coupling transformer. The Thyristor Controlled Reactor (TCR) provides inductive reactive power and controls the active power filter (APF) as the current source, it is connected with the additional inductor La in parallel via the coupling transformer, then connected to the passive filter Zf in serial to consist a hybrid power filter system, which is connected to the power grid via the circuit breaker or thyristor. The comprehensive filter system provides required capacitive reactive power and filters the harmonic produced by the load and TCR system itself. Because the capacity of the active power filter (APF) is very small which is less than 1% of the harmonic source capacity, so it is a solution with low cost but simple and reliable control mode. It can suppress influence on the passive filter by the “background harmonic” of the substation and prevent the resonance occurred between the passive filter and power grid impedance.
    • 本发明公开了一种用于电力系统中变电站的综合功率质量控制器,包括晶闸管控制电抗器(TCR),纯调谐无源滤波器Z附加电感器L有功功率滤波器(APF) 和耦合变压器。 晶闸管控制电抗器(TCR)提供感应无功功率并控制有源电力滤波器(APF)作为电流源,它通过耦合变压器并联连接到附加电感器L& 以串联方式连接到无源滤波器Z N以构成混合电力滤波器系统,该系统通过断路器或晶闸管连接到电网。 综合滤波系统提供所需的电容无功功率,并对由负载和TCR系统本身产生的谐波进行滤波。 由于有源电力滤波器(APF)的容量非常小,小于谐波源容量的1%,因此是一种低成本但简单可靠的控制方式的解决方案。 可以通过变电站的“背景谐波”来抑制无源滤波器的影响,防止无源滤波器与电网阻抗之间发生谐振。

    • Techniques and methods of formation of ordered mixtures of particles by “clustering”. Clustering comprises local “structuring” consisting of a large “host” and smaller “guest” particles by various techniques. Small amounts of polymer are coated onto solid particles by various means. In one embodiment, an ordered mixture is created wherein the material that is of lesser quantity is of small particle size (the “B” particles) and the “A” particles are of larger size. The “B” particles are then coated onto a single A particle. By creating this ordered structure, each composite particle has the proper or stoichiometric amount of all ingredients. This dry composite material produced is appropriately used in various applications such as pharmaceutical formulations in the form of tablets, capsules, oral suspensions, inhalant, parenteral formulations and the like; energetics manufacture such as but not limited to explosives, propellants and pyrotechnics; agricultural products including but not limited to fertilizers, herbicides and pesticides; nutritional supplements and the like.

    • Methods for treating glutaraldehyde-fixed collagenous tissues to mitigate there propensity for subsequent calcification and to improve durability. Collagenous tissues which have been harvested and cross-linked by glutaraldehyde are exposed to a carboxyl activating agent to convert the free carboxyl (COOH) groups of the collagen molecules to activated carboxyl moieties (e.g., o-acylisourea). Thereafter, the collagenous tissue is exposed to a compound capable of reacting with the activated carboxyl moieties (e.g., o-acylisourea) to form non-carboxyl side groups. Monofunctional and multifunctional amines are examples of compounds which may be utilized to react with the activated carboxyl moieties to form such non-carboxyl side groups. Thereafter, the collagenous tissue is again exposed to glutaraldehyde. If the non-carboxyl side groups have functional amino groups (NH.sub.2), such additional exposure to glutaraldehyde will result in additional glutaraldehyde cross-linking of the collagen molecules and resultant improvement of durability.
    • 用于治疗戊二醛固定的胶原组织以减轻随后钙化倾向并改善耐久性的方法。 已经通过戊二醛收获和交联的胶原组织暴露于羧基活化剂,以将胶原分子的游离羧基(COOH)基团转化成活化的羧基部分(例如邻酰基异脲)。 此后,将胶原组织暴露于能够与活化的羧基部分反应的化合物(例如,O-酰基异脲)以形成非羧基侧基。 单官能和多官能胺是可用于与活化的羧基部分反应以形成非羧基侧基的化合物的实例。 此后,胶原组织再次暴露于戊二醛。 如果非羧基侧基具有官能氨基(NH 2),则另外暴露于戊二醛将导致胶原分子的另外的戊二醛交联,从而提高耐久性。
